摘　　要：当通信系统工作于强干扰环境中时,外部干扰对传输信号的不同信息段的干扰程度存在较大差异,在信道解码中对不同的干扰进行加权识别,可以降低强干扰位置对应信息在TPC迭代解码中的可信度,抑制强干扰对TPC解码的性能影响。计算机对比仿真表明加权的TPC算法可以将强干扰导致的高误比特率降到10-3量级。when a communication equipment operation in a heavy jamming circumstance, there are different jamming energy existed in the transmitting signal. The receiving signal can be multiplied by a weight factor ac- cording to the level of jamming, therefore, the reliability of singal under interference will be supressed in TPC decoding process. The computer simulation indicates that the BER of TPC decoder drops to 10-3 from a much high level by using proposed algorithm
